IDG Contributor Network: Technology helps first responders fight California fires

Fires have laid to waste huge swaths of Northern California. The deadly blazes have burned through more than nearly 400 square miles forcing 100,000 people to evacuate, and destroying over 8,400 structures.How do firefighters respond to such a disaster? Where are they dispatched? When and where are evacuations ordered? How can a fire being propelled by 78mph gusts of wind be contained? How do planes know where and when to deploy fire retardant?Sensors, drones, fire-cams, crowdsourcing and geographical information systems all help minimize damage and deaths.To read this article in full or to leave a comment, please click here

IDG Contributor Network: 7 ways IoT is reshaping the internet

Two decades ago, the Internet was the shiny new object in the room. The Worldwide Web was just emerging as a new paradigm for communication and commerce, and the world brimmed with possibilities. Today, not only has the Internet fulfilled those nascent dreams, it has become the undisputed foundation of the digital age.But now there’s a new paradigm in town—the Internet of Things (IoT).For years, IoT has been growing up inside factories and oil platforms, in ships, trucks, and trains—quietly changing long-standing industrial processes. It has made its way into virtually every industry—agriculture, aviation, mining, healthcare, energy, transportation, smart cities, and on and on. IoT is no longer just the next phase of the Internet—it’s fundamentally reshaping the Internet as we know it.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Why edge computing is critical for the IoT

While many of today’s always-connected tech devices take advantage of cloud computing, Internet of Things (IoT) manufacturers and application developers are starting to discover the benefits of doing more compute and analytics on the devices themselves.This on-device approach helps reduce latency for critical applications, lower dependence on the cloud, and better manage the massive deluge of data being generated by the IoT. An example of this trend is the recently announced Nest Cam IQ indoor security camera, which uses on-device vision processing to watch for motion, distinguish family members, and send alerts only if someone is not recognized or doesn’t fit pre-defined parameters. By performing computer vision tasks within the camera, Nest reduces the amount of bandwidth, cloud processing, and cloud storage used versus the alternative of sending raw streams of video over the network. In addition, on-device processing improves the speed of alerts while reducing chances of annoying, recurrent false alarms.To read this article in full or to leave a comment, please click here

The Industrial IoT will give us self-healing machinery

Production downtime’s days are limited thanks to the industrial Internet of Things (IoT). Machine-embedded, network-connected sensors along with the collection of massive amounts of data will allow for self-healing manufacturing, scientists say.That’s the concept behind an enthusiastic research project called SelSus currently being explored by multiple European academic institutions and manufacturers, including Ford.Also on Network World: How industrial IoT is making steel production smarter The idea that the team proposes is to not just detect weaknesses during production, but to also fix the potential issues automatically through a kind of mathematically calculated self-healing. The scientists say diagnostics should supply recommendations before a piece of equipment has failed. That self-healing aspect would take equipment monitoring to the next level.To read this article in full or to leave a comment, please click here

Fidelity Investment’s key to hybrid cloud: Application flexibility

From an infrastructure perspective, Fidelity Investments uses a combination of private cloud hosted in company data centers plus multiple public cloud platforms, leading to the question, how to manage this hybrid infrastructure?One key is being flexible, say Maria Azua Himmel, senior vice president of distributed systems at the 71-year old multi-national with $2.13 trillion in assets under management.Azua is attempting to implement strategies among Fidelity’s application developers to ensure that when new apps are built they can be run in almost any environment, whether it be one of the public clouds the company uses or inside its own data centers. To do this Azua is advocating for the use of application containers and software-defined infrastructure that can be controlled via application programming interfaces (APIs).To read this article in full or to leave a comment, please click here

Hello IPv6, Goodbye CGNs – Recent Discussions at a EU/Europol Meeting

Jan Zorz was recently invited to speak at a workshop held by the Estonian Presidency of the Council of the EU and Europol. Jan gave a well-received talk about how Slovenia widely deployed IPv6 and encouraged EU policymakers and law enforcement officials to do the same across Europe.

Per the press release, the workshop was “to address the increasing problem of non-crime attribution associated with the widespread use of Carrier Grade Network Address Translation (CGN) technologies by companies that provide access to the internet.”

With IPv4 address space depleting, CGNs have been widely implemented to conserve public IPv4 address space. In other words, many customers are sharing a single public IPv4 address that often also changes over time. Problems with sharing IP addresses (and therefore CGNs) are well outlined in RFC 6269: “Such issues include application failures, additional service monitoring complexity, new security vulnerabilities, and so on.”

CGNs also present a problem for law enforcement agencies looking to investigate and prosecute crimes online, as it’s much more difficult to narrow down the culprit. This workshop had several IPv6 experts speak of their experiences, partially on the assertion that IPv6 deployment would eliminate CGNs and once again Continue reading

CLI or API… Again (and Again and Again…)

Got this comment on one of my blog posts:

When looking at some of the CLIs just front-ending RESTAPIs, I wonder if "survival" of CLI isn't just in the eyes of the beholder.

It made me really sad because I wrote about this exact topic several times… obviously in vain. Or as one of my network automation friends said when I asked him to look at the draft of this blog post:

Is my TPM affected by the Infineon disaster?

I made a tool to check if your TPM chip is bad. Well, it extracts the SRK public key and you can then use marcan’s tool to easily check if the key is good or bad.

Example use:

$ g++ -o check-srk -std=gnu++11 check-srk.cc -ltspi -lssl -lcrypto 2>&1 && ./check-srk
Size: 2048
Outputting modulus…

$ wget https://gist.githubusercontent.com/marcan/fc87aa78085c2b6f979aefc73fdc381f/raw/526bc2f2249a2e3f5d4450c7c412e0dbf57b2288/roca_test.py

$ python roca_test.py 8490234823904890234823904823904890238490238490238490238490[…]893428490823904231
Vuln!

(use -s if you have an SRK PIN)

If the SRK is weak then not only are very likely anything else you generated in the TPM weak, but also anything generated outside the TPM and imported is crackable, since your blobs are encrypted using this crackable SRK key.

How to Monkey-Patch the Linux Kernel

I have a weird setup. I type in Dvorak. But, when I hold ctrl or alt, my keyboard reverts to Qwerty.

You see, the classic text-editing hotkeys, ctrl+Z, ctrl+X, ctrl+C, and ctrl+V are all located optimally for a Qwerty layout: next to the control key, easy to reach with your left hand while mousing with your right. In Dvorak, unfortunately, these hotkeys are scattered around mostly on the right half of the keyboard, making them much less convenient. Using Dvorak for typing but Qwerty for hotkeys turns out to be a nice compromise.

But, the only way I could find to make this work on Linux / X was to write a program that uses X "grabs" to intercept key events and rewrite them. That was mostly fine, until recently, when my machine, unannounced, updated to Wayland. Remarkably, I didn't even notice at first! But at some point, I realized my hotkeys weren't working right. You see, Wayland, unlike X, actually has some sensible security rules, and as a result, random programs can't just man-in-the-middle all keyboard events anymore. Which broke my setup.

Yes, that's right, I'm that guy:

IDG Contributor Network: The 4 SD-WAN architectures for network security

SD-WAN might have begun as a networking technology, but the SD-WAN’s future lies in security. Integrating branch security features into SD-WAN, allow leaner, simpler remote office deployments.  To those ends, security vendors have introduced SD-WAN capabilities — and SD-WAN vendors add security capabilities.1. SD-WAN appliances with basic firewalling Many SD-WAN vendors deliver basic firewalling capabilities in their SD-WAN appliances. These firewalls are roughly equivalent to the stateful firewalls you might see in a branch office router. Capabilities will include policy-based filtering and blocking applications based on port or IP addresses. Examples include Cisco (Viptela), Silver Peak and Velocloud.To read this article in full or to leave a comment, please click here

Think Of Your Audience

One of the challenges technical authors face is that of peer respect. That is, technical people who took a lot of time to learn what they know want to be respected by their peers when they write. They want to be recognized for their knowledge, wisdom, and insights.

In that context, there’s often fear before pressing “Publish.” Was every detail correct? Was every scenario considered? Was the very latest information about a topic included?

The fear of hitting publish is well-founded for technical authors, because technical folks have a way of being nit-picky, pedantic, and annoying. One small detail wrong, one badly stated premise, and the angry comment and critical tweet claws come out, slashing at your ego.

Will they like me? I just want everyone to like me.

One solution, of course, is to have a thick skin. If you view criticisms as a way to improve a piece, that’s the best route to go, especially when the commenter has a good point. Being able to ignore critics is another useful skill, because there are plenty of folks who say a lot while adding no value whatsoever.

However, I think the most important point to keep in mind Continue reading
